Daturas: Can I move my datura plant at this point?

One of my purple metel datura seedlings in the garden had a difficult time coming back to life after it had been chomped down by a hornworm. I put it in a pot and babied it, and it came back, but I didn't have great hopes for it. I put it back in the garden, and now it's thriving. Problem is, I planted it too close to another plant, thinking it would remain a runt, and the leaves are getting so big, it's going to completely take over the now smaller plant! The dat is about 1 1/2 feet tall; would it be risky to try to uproot it to move it to a roomier spot?
